Illumination device cooling module and cooling device including same

Abstract

A cooling module for illumination device, includes: a substrate contacting a heat-generating illumination part at a lower part thereof and having an insertion groove formed on the upper surface thereof; a heat pipe which radiates the heat generated from the illumination part and includes a horizontal part inserted into the insertion groove and a vertical part vertically bent from the horizontal part and extending in a longitudinal direction; and a heat radiating plate laminated on and coupled to the vertical part of the heat pipe to promote heat radiation of the heat pipe, and including a coupling part coupled to the heat pipe, an inner fin part cut inward from the coupling part and formed to be twisted by a predetermined angle, and an outer fin part cut outward from the coupling part and formed to be twisted by a predetermined angle.

The invention claimed is: 
     
       1. A cooling module for illumination device, the cooling module comprising:
 a substrate contacting a heat-generating illumination part at a lower part thereof and having an insertion groove formed on the upper surface thereof; 
 a heat pipe which radiates the heat generated from the illumination part and includes a horizontal part inserted into the insertion groove and a vertical part vertically bent from the horizontal part and extending in a longitudinal direction; and 
 a heat radiating plate laminated on and coupled to the vertical part of the heat pipe to promote heat radiation of the heat pipe, and including a coupling part coupled to the heat pipe, an inner fin part cut inward from the coupling part and formed to be twisted by a predetermined angle, and an outer fin part cut outward from the coupling part and formed to be twisted by a predetermined angle, 
 wherein the inner and outer fin parts are divided into a first height portion having a predetermined height from a bottom and a second height portion having a height from the first height to a top, 
 wherein the inner and outer fin parts of the second height portion are formed to be twisted by an angle relatively larger than the inner and outer fin parts of the first height portion, 
 wherein the inner and outer fin parts of the first height portion promote heat radiation to a lateral side and the inner and outer fin parts of the second height portion promote heat radiation upward. 
 
     
     
       2. The cooling module of  claim 1 , wherein the insertion groove and the horizontal part of the heat pipe are formed in a longitudinal direction toward a center of the substrate respectively, and have one side formed to be biased and inserted while progressing toward the center of the substrate. 
     
     
       3. The cooling module of  claim 2 , wherein the insertion groove and the horizontal part of the heat pipe are formed to be bent at least once. 
     
     
       4. A cooling device having a cooling module for illumination device, the cooling device comprising:
 the cooling module of  claim 1 ; 
 an illumination part attached to a lower portion of the cooling module; and 
 a case which accommodates the cooling module and the illumination part, and has a vent hole. 
 
     
     
       5. The cooling device of  claim 4 , wherein the case further comprises a visor so as to control a path of light emitted from the illumination part. 
     
     
       6. A cooling module for illumination device, the cooling module comprising:
 a substrate contacting a heat-generating illumination part at a lower part thereof and having an insertion groove formed on the upper surface thereof; 
 a heat pipe which radiates the heat generated from the illumination part and includes a horizontal part inserted into the insertion groove and a vertical part vertically bent from the horizontal part and extending in a longitudinal direction; and 
 a heat radiating plate laminated on and coupled to the vertical part of the heat pipe to promote heat radiation of the heat pipe, and including a coupling part coupled to the heat pipe, an inner fin part cut inward from the coupling part and formed to be twisted by a predetermined angle, and an outer fin part cut outward from the coupling part and formed to be twisted by a predetermined angle, 
 wherein the inner fin part is formed to be twisted by a relatively larger angle than the outer fin part, 
 wherein the outer fin part promotes heat radiation to a lateral side and the inner fin part promotes heat radiation in an upward tilt direction. 
 
     
     
       7. The cooling module of  claim 6 , wherein the inner fin part comprises a first inner fin part adjacent to the coupling part and a second inner fin part extending from the first inner fin part,
 wherein the second inner fin part is formed to be twisted by a relatively larger angle than the first inner fin part, 
 wherein the first inner fin part promotes heat radiation in an upward tilt direction and the second inner fin part promotes heat radiation upward.
